This is called as name Burford 'Mad Dog' Tannen on the movie as Back to the Future part III. It's is in the old west by the back into 1885. It's is bad person on the wild wild old west. Well, hope you will like this one!!!!

Is there a possibility of Aeromexico fitting winglets on their new birds? Are winglets even an option on the 736? It seems to me that they are common on the 737-700 and -800 models. Winglets would certainly give their new birds an added touch.

SAS is apparently not very satisfied with their 736s. The fuelconsumption is too high for a brand new aircraft like that and the 736 is very sensitive when it comes to turbulence. This is due to the combination of a modest length, wide wings and a long tailfin.
I was recently on a SK flight between NCE and CPH performed by a 736. The aircraft was shaking so much during the entire flight for over 2 hrs. that it was impossible to eat or drink anything. When we were on the ground a crewmember confessed that this was not very uncommon for a 736. According to some sources SK is however very pleased with the 737-700 and 800-series.
But perhaps AMX still have a possibility to go for the A319 instead?

ARN is completely correct on SAS' experience with the 736.It is presently on the top of the SAS "transfer list" but so far no takers.Airbus proposed to take the 736's as part payment for additional A32x orders a few years ago but not anymore!As the operational expenses and flying qualities of the 736 became known,almost all orders for the type were changed to the 737-700 and the 737-800.In SAS,the -700 is just "so-so",while the -800 is in fact a money-maker.Unless Aeromexico/Boeing would consider leasing the 736's from SAS,it seems we will be stuck with these "piglets" forever.

Interesting choice and good for Boeing......the 736 will replace the DC9-30s still in service, and, hopefully AM will follow up with orders for the larger members of the 737NG family to replace, over time, the MD80s family aircraft. I think that AM will be very interested in the 738, which is a far more flexible aircraft than the MD80s, and operate transborder flights from MEX and other cities to just about any destination in the US, Canada and the northern half of South America.

As for the 736 not riding as well as other members of the 737NG family, these reports are far exagerated and the 736 does not handle much differently than the 735, or the "original 737-200", all of which have about the same length fuselage. SAS was not 100% satisfied with the 736's fuel economy, but it is well within the parameters set forth by Boeing.....it is not unusual for the smallest member of an aircraft family to have the "worst" fuel characteristics when analyzed on a fuel per seat basis.

Dutchjet has a good point. If the 737-600 operates so poorly and uneconomically, why does Boeing continue to market the product? SAS may not be 100% satisfied with the product, but that doesn't necessarily mean that it's a bad product. The 736 simply didn't meet their expectations.
